Question about tracking user in a map application using cellid

Question

I am trying to understand the concept of cellid (http://www.opencellid.org/api)

As per that, if we send a request

http://www.opencellid.org/cell/get?key=myapikey&mnc=1&mcc=2&lac=200&cellid=234

it will respond with the latitude and longitude.

I was wondering if this can be used from within a google map application for tracking a user or it needs to be used from within a mobile device?

If it can be used from within a web app, what parameters should it use for

mcc: mobile country code (decimal) mnc: mobile network code (decimal) lac: locale area code (decimal) cellid: value of the cell id

E.g., will it work if we know the cell number of the person(e.g., 281 222 6700)

Answer 1

The request is just a lookup in the opencellid database.

It doesn't matter where the information is coming from.
If you know the MMC, MNC, LAC and CellID of a user/mobile device,
the request will return latitude and longitude if the cellID has been found in the DB.

There is no additional information transfered by using the request from within a J2ME app.
MCC+MNC+LAC+CELLID should be a unique identifier of a cell. (afaik those values can change over time, but they still should be unique.)
